Allow Numeric Slugs

Description

Normally it is not possible to have a page slug (the page’s name in the URL) that is a number. For example this will not work: yoursite.com/about/2/. That URL conflicts with paged content feature where you can posts and pages with multiple pages of content by adding <!--nextpage--> within your content.

This plugin allows you to have pages with numbers as slugs by giving up the ability to have paged content pages which isn’t a big deal as most people don’t use paged content pages anyway.

This have been bugging me for soooo long. Finally a way to make pretty URLs. Before WordPress just added a "-2", and the end, but now it's displayed as I wanted it.
Example:
Before: site.com/pictures/2016-2/
Now: site.com/pictures/2016/
